    Anyone familiar with silk peptides?  Thinking of what would be the best product to incorporate them into.

    @Jdawgswife76 I regret buying them. I tried to incorporate them in hair conditioner. The smell  was unbearable.

    I have made face mask formulations which are quite good, and once played with incorporating a natural source substance found in some banks of underground streams.  But, I ran into the bacterial elimination problem and ended up using commercially available sterilized clays. 

    The relevant information as relates to your situation is that your access to the natural material might not be as good fortune as you envision.  You would need to start out with a sterilized clay base and sterilizing that material with an appropriate heating situation (oven) may cause changes in its properties that would make it unsuitable.  An option other than heat is radiation. I found two places, one in Canada and another in Texas.  You can Google for places which will do that for you. I have tested them for other applications and they are amazing in their completed sterilization of plant origin materials which are loaded with bacterial substances and other organisms in their supplied state. Sterilized clays are readily available.  So, that might be your best option.

    As far preservatives, you might want to experiment with Optiphen Plus. It’s made by Ashland Chemical. It now has global approval and it is paraben-free and formaldehyde-free.  It meets modern market expectations for a preservative system,

    @Doreen
    Yes, I have received a new patch of phenoxyethanol and the scent outcome remains, unfortunately, the same.

    @perspicacious
    It is encountering to hear that there are more people experiencing difficulties with the bacterial elimination from fully natural material.
    Bypassing excitement is slowly replaced with the actual knowledge of the material itself and therefore I can say that there truly are multiple factors affecting the outcomes of different testings. Lots of characteristics to consider working with the material.

    It is overwhelming to hear that you end up mentioning radiation since this week I ordered sterilization tests with my material through 10 kGy gamma radiation ( Cobalt 60 isotope ). Of course, it is expensive and pretty bad market-wise for dilettants but the actual effect of it should be outstanding considering the situation with my complex, yet good and natural material.
    At least i think and hope so.

    Offtopic:

    Have anyone had experience with the registration of cosmetic product which has been sterilized through gamma radiation? ( Haven’t had time to check it’s compatibility with the EU cosmetic law, does the manufacturer have any duties of informing the customer about sterilization process?…)

    I will let you know about the outcome of tests!

    Thanks for everyone

    Can you buy directly from Shulke 9010, it comes with ethylhexylglycerin and I have never had a problem with odour. Hope this helps

    Neither have I, I kinda like the scent! But I’m afraid if you don’t like the smell of phenoxy, you’re not going to like Euxyl PE 9010 either.

    Honestly, at the levels used, Euxyl PE9010 has little to no influence on the final fragrance in the finished product. Ensuring that a chelant is used and being aware that it can destabilize an emulsion are the biggest concerns.

    Yes I agree, plus you need to get some practice at masking bad odours, or no-one would wash, use make-up or brush their teeth!

    I smell a slight rose-like floral scent. There are some members here (older posts in this thread) who absolutely dislike the smell and describe it otherwise.

    I think so too. Even in a fragrance free formula with 1% Euxyl PE9010.

    @ngarayeva001 the silk smells peptides smell bad or just in the conditioner?  Im thinking of the powder and conditioner would be the fist place i would look to put them but not if they stink.

    @Jdawgswife76
    The smell is there in any formula, depending on %.
    I found it hard to mask with fragrance in the recommended %.
    You could use it as claims ingredient at 0.1%, or so?

    So i have ran into a preserving issue with making clay masks with kaolin,  indian healing,  Moroccan,  and french green as well as black charcoal.  Anyone have any suggestions on a good preservative for these for a good shelf life?

    I really dislike smell of phenoxyethanol. @Jdawgswife76, it’s very difficult to preserve clay based product. It deactivates phenoxyethanol and some other preservatives. I recently bought phenonip, it’s phenoxyethanol and a mix of several parabens. Should be a very strong preservative, but haven’t tested yet.

    Can you lmk how it works out for you using that preservation system?  Im really wanting to make up and package some masks but of course want to be sure they are very well preserved.

    Would the powder smell the same way you  think?  The powder has great benefits for the skin and is great in creams,  powders,  foundations,  etc but i have never noticed a smell of any kind from the powder i have.

    @Jdawgswife76 what is INCI of the product you are using? It should be some type of protein (amino acids, peptides) to have skin benefits (not really proven) and proteins often have horrible smell. Also proteins compromise viscosity of certain polymers. I recommend you to start a new topic about benefits of silk. Let’s see what professionals think and is there any proof that silk even does anything for skin.
